Atari Foundry · Micro Lab for 400/800, XL, XE

We build weird Atari 8-bit things because we can.

Software, hardware, merch—whatever keeps these machines interesting.

We’re a mad-science shop for Atari 8-bit computers. We prototype languages, flash cartridges, solder interface boards, write manuals, screen-print faceplates, and then toss everything into the vault so other builders can play along.

If it runs on 400/800, XL, or XE and sounds fun, we’re probably already hacking on it. Come raid the shelves.

What’s cooking

Software drops

Languages, utilities, test harnesses, and disk tools compiled straight to 6502.

Hardware builds

Cartridges, interface boards, and diagnostics rigs—documented with BOMs and solder notes.

Weird peripherals

Faceplates, badge kits, stickers, and other lab souvenirs for your Atari bench.

Media-ready releases

ATRs, cassette masters, and ROM images that ship with checksums and duplication guidance.

Docs & lore

Markdown manuals, schematics, and notebooks so you can see how the experiments came together.

Lab rules

Real hardware only

Everything gets burned onto actual cartridges, disks, or tapes before it leaves the bench.

Share the schematics

Build logs, wiring diagrams, and BOMs go public so you can recreate (or improve) the work.

No committees

If it sounds fun, we build it. If it’s useful, it ends up in the vault. Simple as that.

Goods for sale

Finished boards, merch, or media runs show up in small batches. Miss it? Wait for the next experiment.

Atari obsessed since ’78

We grew up on 2600s, 400/800s, XL/XEs, and crusty BBS lines. That history leaks into every release.

How we ship

  • Sketch it, solder it, or code it late at night. Write everything down.
  • Test on real hardware until the smoke clears.
  • Bundle ATR/ROM, docs, BOMs, and notes—drop into the vault.
  • Announce it, sell a few units or give it away. Move to the next obsession.

How to follow along

  • Project log → `/about` for the mission, milestones, and build philosophy.
  • Vault → `/vault` for product information and downloads.
  • Support & chat → `/support` for issues, Discord, and Atari BBS breadcrumbs.

The lab door’s open.

We build the stuff we want to see on Atari 8-bit hardware—share it, sell it, or stash it in the vault. Come tinker, buy a board, or steal the plans. It’s all part of keeping these machines alive.
